Linkkilohkoina

Linkkilohkoina is a Finnish term that translates to "link locks" or "link chains" in English. It refers to a type of historical maritime mooring device used in harbors and ports. These devices were typically heavy metal rings or loops anchored to the seabed or a solid structure, designed to provide a secure point for vessels to tie up.

The primary purpose of linkkilohkoina was to offer a more robust and permanent mooring solution than individual buoys or simple anchorages. They were particularly useful in areas with strong currents or tides, where a stable connection was essential to prevent ships from drifting. In many cases, these link locks were part of a larger mooring system, often connected by heavy chains or thick ropes to a central anchor or a series of distributed anchors.

The construction of linkkilohkoina varied depending on the era and the available materials, but they were generally made from cast iron or heavy steel. The design prioritized strength and durability to withstand the immense forces exerted by large ships and harsh weather conditions. Archaeological evidence and historical port records sometimes mention the presence and layout of these link locks, offering insights into ancient and medieval maritime infrastructure.

While modern mooring techniques have largely superseded the use of traditional linkkilohkoina, remnants of these historical devices can still be found in older harbors. They serve as a tangible link to the past, illustrating the ingenuity and practical solutions employed by seafarers and port builders throughout history. Their presence indicates a well-established port that required secure and reliable docking facilities for vessels.
